Crash when exiting PIE mode #345

Open staskjs opened 2 years ago

staskjs commented 2 years ago

I use UE 5.0.3, plugin version 2.4. It happens occasionally, happened in 2.3 also. It always happens when I exit play mode and I only use functionality that plugin provides without this lower level stuff. I guess something doesn't close properly or interrupted somehow UPD: it sometimes happens in packaged game too. But sadly I can't notice any pattern...

Platform? How are you using the plugin, through component or native method? https or http? Does changing Unbind Events on Disconnect stop this error for you?

It's also possible the disconnect thread is behaving differently for you (async disconnect is default, but I've never seen this error personally)

staskjs commented 2 years ago

It's on windows. I use components, instantiated at runtime in game instance. Https. I haven't checked Unbind Events on Disconnect, but I will try, thanks for the tip. I'll get back here if problem persists.

Unbind Events on Disconnect doesn't seem to help. I think I figured out how to reproduce the issue. I put Join namespace in a umg widget on socket connected event. Then in widget's Destruct I was calling Leave namespace. Then Alt+F4 causes game to crash. But I didn't need to leave namespace after all, so it is fine for now...
